In the 375 H&H I use WW 760 for the 275 BBC...I have used this load to dispatch my NA bears...
a friend of mine likes 4064 for 250s, WW 760 for 270s and IMR 4831 for the 300...

I have been told by a guy that pressure checked for the 375 H&H that RL-17 was the best powder for 300 grains and up.At factory velocities the pressure was low and for the heavier weights,his reply was,it really made them scream!!!

RL-15 hands down -- at least for my rifle. 270 TSX and 73.5 grains of 15 is like "buttah."

Well, based on preliminary shooting of the 300 gr. DGX and DGS, with H4350, I'll be doing a lot more testing with that powder.

I second the RL17. I've tried H4350, RL15, 760/414, and Big Game. RL 17 gives the best pressure/velocity readings with the 300gr Swift A-frame. I've had around MOA accuracy with all of them but RL17 is the most consistent and I'm getting 2615 fps without any pressure. I've reached pressure signs at about 2550-2575 with the other powders mentioned. I actually had no pressure up to 2675 with RL17 but found a more accurate load down around 2600.
I'm headed to the range again today. I leave on Tuesday for my Zim Buff hunt. Wish me luck! Lee

What powder works in someone elses gun may or may not mean a thing in your gun..You have to discover that for yourself..Fortunately for you you picked a caliber that is EASY to load for and most are not picky..
I always try IMR-4064, H4350 or RL-15, to start with, but have had luck with IMR-4895, WW-760, H414..
